(6.) How much work was done during the 1000m of the race?

Given Information:

During a bicycle race, a cyclist who had a mass of 50kg used a bike with a mass of 20kg. As he began the race, he was able to displace 100m the first 10sec of the race. As the race continued, his velocity increased to 25m/s at exactly 20sec of the race. He was able to maintain this acceleration for a total of 1000m.
Possible Answers
1050kJ
70000J
75000J
1500J
1500N

Sorry There's so many, This isn't all of them F.Y.I. so I wasn't just like "hey man do this all for me." There's 57 questions, these are just the one's that I can't do. Please help me out! I have a spliting headache and I am EXTREMELY stressed out. Thank you!!!!!!1. The problem statement, all variables and given/known data

I'm sorry that you have a headache, but, asking us for the answers to 25 out of 57 problems without an attempt at a solution is moving beyond the realm of "homework help" and into the realm of "doing homework for you".
